Low-odor hair waving agent and preparation method thereof

Technical Field

The present application relates to the field of permanent waves, and more particularly, to a low odor permanent wave agent and a method for preparing the same.

Background

The cross section of hair can be divided into hair epidermis, hair cortex and hair medulla from outside to inside. Mao Biaopi the hair scale, which is the outermost layer of the hair shaft, consists of scales and tile-like cells. The hair epidermis contains a large amount of high sulfur protein, which plays a good role in protecting the hair.

The hair waving is popular in the market, namely, hair scales are opened through ammonia water and the like, disulfide bonds are opened, hair is softened, disulfide bonds are reformed at new positions through a weak oxidant, protein chains are rearranged according to the straightened shape of hair curls or splints, and the hair is dried to form a specific waving or straightening shape.

The ammonia water has larger pungent smell in the use process; while hair salons are generally limited in area, ventilation is also common. Under these conditions, this large amount of pungent odor easily causes physiological discomfort to the customer and the stylist. Therefore, there is still a need for improvement.

Disclosure of Invention

In order to reduce the odor of the permanent waving agent, the application provides a low-odor permanent waving agent and a preparation method thereof.

In a first aspect, the present application provides a low odor permanent wave agent, which adopts the following technical scheme:

a low-odor permanent wave agent comprises the following components in percentage by mass: 5-10% of ammonium thioglycolate, 1-5% of humectant, 0.01-2% of antibacterial agent, 0.1-2% of emulsifier, 1-5% of alcohol solvent, 0.1-3% of ethanolamine, 0.1-3% of conditioner, 0.01-3% of chelating agent, 0-1% of essence, 0-6% of supplement, 0.1-5% of triethyl citrate, 1-5% of persimmon tannin extract, 0.1-1% of argania spinosa kernel oil, 0.1-1% of camellia extract, and the balance of water is added to 100%.

By adopting the technical scheme, the ethanolamine is selected as the base, so that the irritation taste generated by the ethanolamine is weak, and the pungent taste generated by the permanent waving agent can be effectively reduced.

However, in practical research and development, it was found that although the use of ethanolamine can effectively reduce odor, the alkalizing effect is deteriorated, and the shaping effect of permanent waves is affected. Therefore, the technical scheme of the application further selects the specific persimmon tannin extract, the argyi tree kernel oil and the camellia extract, and under the special matching of the three, the perming agent can be quickly mixed with the grease of the hair, so that a thin porous film is formed on the surface of the hair, various active ingredients of the perming agent are promoted to diffuse on the hair along the porous film, the active ingredients are easier to act on the positions of the cuticle and the hair scale, more hair scales are easily and naturally opened, more hair keratin is promoted to expand, the follow-up oxidizing agent and the like are convenient to enter, the shaping effect is improved, and the residual smell is reduced. That is, although the alkalizing effect of ethanolamine itself is general, the permanent waving agent of the present application gives full play to the effect of ethanolamine and is combined with other raw materials to assist ethanolamine in playing a role, thereby improving the shaping effect while reducing odor.

The hair waving is to use a chemical method to break disulfide bonds of cystine in hair due to reduction, then use a physical method to deform the hair through a curling bar or a clamping plate, and finally oxidize cysteine by using an oxidant (hydrogen peroxide or sodium bromate) to form cystine at a new position, thereby realizing curling or straightening of the hair. However, in the process of perming hair, disulfide bonds between polypeptide chains are easily excessively reduced when disulfide bonds are cut, so that the protein content in hair is reduced, and the hair after perming is fragile and easily broken.

Preferably, the emulsifier comprises at least one or more of glycerol stearate, cetostearyl alcohol polyether-25.

Preferably, the emulsifier is glycerol stearate and cetostearyl ether-25, wherein the mass percentage of the glycerol stearate in the hair waving agent is 0.4-0.8%, and the mass percentage of the cetostearyl ether-25 in the hair waving agent is 0.5-1%.

By adopting the technical scheme, the specific emulsifier is further selected and mixed in the system with specific dosage, so that the raw materials such as the argania spinosa kernel oil and the like can be promoted to be more fully mixed with other raw materials, an emulsion system is formed rapidly and stably, and the mixing effect among the raw materials is fully exerted. Meanwhile, the porous membrane formed specially can be used for fully soaking the surface of the hair, and the shaping effect of the hair waving agent on the hair is enhanced.

Preferably, the weight percentage of the triethyl citrate in the perming agent is 0.5-2%.

By adopting the technical scheme, the usage amount of the triethyl citrate in the hair waving agent is further limited, so that the hair waving agent is coated and formed on the surface of the hair more rapidly, and the opening of the hair scales is promoted.

In a second aspect, the present application provides a method for preparing a low-odor permanent waving agent, which adopts the following technical scheme: a preparation method of a low-odor permanent wave agent comprises the following steps:

mixing water, ammonium thioglycolate, humectant, antibacterial agent and emulsifier at 75-85deg.C, and stirring to dissolve uniformly;

Step 06): and removing the hair curler, and flushing the hair bundles after ironing with normal-temperature tap water for 30s to obtain the hair bundles after ironing.

Each test sample corresponds to 5 hair strands.

3. Detecting items:

1) Odor detection effect:

volunteer selection: 15 sniffers with ages of 18-45 years and no smoking and no smell and no disease are selected. The olfactory reader should be the olfactory qualified person detected and screened according to GB/T14675-1993 standard.

The detection method comprises the following steps: naturally hanging the hair bundles corresponding to each detection sample, and placing the hair bundles in an environment with relative humidity of 65% and temperature of 25 ℃.

The distance between the nose tip of the volunteer and the surface of the hair bundle was 5cm, and the volunteer examined each group of hair bundles and scored the smelling results.

Taking 0-10 as a scoring range, wherein the score is not necessarily an integer; the higher the score, the heavier the taste; the lower the score, the lighter the taste.

The average score of the 10 sniffers on the hair bundles treated by the same group of detection samples is the detection result of the group and is recorded in table 2.

2) Hair toughness effect: the post-ironing hair tress treated with each test sample was tested according to T/GDCDC 012-2020, evaluation method of the toughness efficacy of Hair products, and tensile Strength was recorded in Table 2.

3) Curling degree of perm: naturally suspending the hair bundles corresponding to each detection sampleHanging, balancing in environment with relative humidity of 65% and temperature of 25deg.C for 24 hr, measuring length in vertical direction in natural hanging state, and recording as L _p . The degree of curl was then calculated according to the following formula and recorded in table 2.

Wherein:

L ₀ the initial length of the hair bundle after ironing is cm;

L _p the length of the hair bundle in the vertical direction after being balanced for 24 hours is cm after ironing.

TABLE 2

Comparative example 5 was intended to simulate a commercial hair waving agent, omitting the core materials of the present application, persimmon tannin extract, argania spinosa kernel oil, camellia extract, and replacing ethanolamine with ammonia water. As can be seen from comparison of the test data of example 1 and comparative example 5 in Table 2, although comparative example 5 has a good curling effect, the odor is heavy and large, and the damage to hair is also large (particularly, the tensile strength of the hair bundle is low). The hair waving agent provided by the application can greatly reduce the smell of the hair waving agent, has good curling effect, and can also supplement nutrition to hair, so that the hair after being scalded is stronger.

The permanent waving agent of comparative examples 1 to 3 was prepared by breaking a specific combination of persimmon tannin extract, argania spinosa kernel oil, and camellia extract on the basis of example 1. As can be seen from comparison of the test results of example 1 with comparative examples 1-3 in Table 2, the odor of comparative examples 1-3 was heavier than that of example 1, the tensile strength of comparative examples 1-3 was also lower than that of example 1, and the degree of curling was not as good as that of example 1. It is described that the specific formulation cannot be developed after the formulation of the specific permanent wave agent of the present application is destroyed.

In combination with comparative example 4, comparative example 4 contained persimmon tannin extract, argania spinosa kernel oil and camellia extract, but the specific amounts of the three to be blended in the system were destroyed. From the examination data of Table 2, it is clear that the permanent wave agent of comparative example 4 is slightly better in all respects than that of comparative examples 1 to 3, but is not significantly better than that of example 1. The method has the advantages that the system is ensured to contain persimmon tannin extract, argania spinosa kernel oil and camellia extract, and the dosage coordination relation of the persimmon tannin extract, argania spinosa kernel oil and camellia extract in the system is further strictly limited.

As is clear from comparison of the results of the tests of example 1 and example 6 in Table 2, the test of example 6 was slightly inferior to that of example 1 in terms of smell, tensile strength and curl, and it was revealed that the kind and the ratio of the emulsifier to be used were further limited, which was advantageous in sufficiently exhibiting the blending effect between the respective raw materials.

Although example 7 increased the amount of triethyl citrate compared to example 1, it is clear from comparison of the test results of example 1 and example 7 in Table 2 that the effect of example 7 was not significantly improved in all respects, probably because the balance of the system was changed due to the action of increasing the amount. The explanation further limits the specific dosage of the triethyl citrate in the system, which is beneficial to fully exerting the effect and is not easy to cause the waste of raw materials.

Example 8 is a supplement whose type and amount are changed based on example 1, and it is understood from comparison of the test data of example 1 and example 8 in table 2 that the performance of example 8 in terms of smell, tensile strength, etc. is degraded. The selection and the dosage proportion of the supplement are further limited, so that the effects of forming covalent bonds between the permanent waving agent and residual sulfhydryl groups and removing peculiar smell are enhanced, and meanwhile, the system can be balanced, and the effects of all aspects are improved.

The present embodiment is merely illustrative of the present application and is not intended to be limiting, and those skilled in the art, after having read the present specification, may make modifications to the present embodiment without creative contribution as required, but is protected by patent laws within the scope of the claims of the present application.
